Queen Elizabeth has tested positive for COVID-19.
Buckingham Palace says the 95-year-old British royal is experiencing mild cold-like symptoms but expects to continue light duties at Windsor next week.
They've previously confirmed she received both doses of a COVID-19 vaccine in early 2021, with UK media reporting she had also received a booster.
In a statement, the palace said the Queen will "continue to receive medical attention and will follow all the appropriate guidelines".
The Queen's eldest son Prince Charles also recently tested positive for COVID - the second time he has contracted the virus - but has since fully recovered.
Queen Elizabeth has had a number of health issues in recent times.
Last October she was unable to attend a centenary service in Northern Ireland after being advised by doctors not to travel.
